Fog computing, applications , security and challenges, review
The internet of things originates a world where on daily basis objects can join the internet and interchange information and in addition process, store, gather them from the nearby environment, and effectively mediate on it. A remarkable number of services might be imagined by abusing the internet of things. Fog computing which is otherwise called edge computing was introduced in 2012 as a considered is a prioritized choice for the internet of things applications. As fog computing extend services of cloud near to the edge of the network and make possible computations, communications, and storage services in proximity to the end user. Fog computing cannot only provide low latency, location awareness but also enhance real-time applications, quality of services, mobility, security and privacy in the internet of things applications scenarios. In this paper, we will summarize and overview fog computing model architecture, characteristic, similar paradigm and various applications in real-time scenarios such as smart grid, traffic control system and augmented reality. Finally, security challenges are presented
On participatory service provision at the network edge with community home gateways
Edge computing is considered as a technology to enable new types of services which operate at the network edge. There are important use cases in ambient intelligence and the Internet of Things (IoT) for edge computing driven by huge business potentials. Most of today's edge computing platforms, however, consist of proprietary gateways, which are either closed or fairly restricted to deploy any third-party services. In this paper we discuss a participatory edge computing system running on home gateways to serve as an open environment to deploy local services. We present first motivating use cases and review existing approaches and design considerations for the proposed system. Then we show our platform which materializes the principles of an open and participatory edge environment, to lower the entry barriers for service deployment at the network edge. By using containers, our platform can flexibly enable third-party services, and may serve as an infrastructure to support several application domains of ambient intelligence.Peer ReviewedPostprint (author's final draft
Combining edge and cloud computing for mobility analytics
Mobility analytics using data generated from the Internet of Mobile Things
(IoMT) is facing many challenges which range from the ingestion of data streams
coming from a vast number of fog nodes and IoMT devices to avoiding overflowing
the cloud with useless massive data streams that can trigger bottlenecks [1].
Managing data flow is becoming an important part of the IoMT because it will
dictate in which platform analytical tasks should run in the future. Data flows
are usually a sequence of out-of-order tuples with a high data input rate, and
mobility analytics requires a real-time flow of data in both directions, from
the edge to the cloud, and vice-versa. Before pulling the data streams to the
cloud, edge data stream processing is needed for detecting missing, broken, and
duplicated tuples in addition to recognize tuples whose arrival time is out of
order. Analytical tasks such as data filtering, data cleaning and low-level
data contextualization can be executed at the edge of a network. In contrast,
more complex analytical tasks such as graph processing can be deployed in the
cloud, and the results of ad-hoc queries and streaming graph analytics can be
pushed to the edge as needed by a user application. Graphs are efficient
representations used in mobility analytics because they unify knowledge about
connectivity, proximity and interaction among moving things. This poster
describes the preliminary results from our experimental prototype developed for
supporting transit systems, in which edge and cloud computing are combined to
process transit data streams forwarded from fog nodes into a cloud. The
motivation of this research is to understand how to perform meaningfulness
mobility analytics on transit feeds by combining cloud and fog computing
architectures in order to improve fleet management, mass transit and remote
asset monitoringComment: Edge Computing, Cloud Computing, Mobility Analytics, Internet of

6G White Paper on Edge Intelligence
In this white paper we provide a vision for 6G Edge Intelligence. Moving towards 5G and beyond the future 6G networks, intelligent solutions utilizing data-driven machine learning and artificial intelligence become crucial for several real-world applications including but not limited to, more efficient manufacturing, novel personal smart device environments and experiences, urban computing and autonomous traffic settings. We present edge computing along with other 6G enablers as a key component to establish the future 2030 intelligent Internet technologies as shown in this series of 6G White Papers. In this white paper, we focus in the domains of edge computing infrastructure and platforms, data and edge network management, software development for edge, and real-time and distributed training of ML/AI algorithms, along with security, privacy, pricing, and end-user aspects. We discuss the key enablers and challenges and identify the key research questions for the development of the Intelligent Edge services. As a main outcome of this white paper, we envision a transition from Internet of Things to Intelligent Internet of Intelligent Things and provide a roadmap for development of 6G Intelligent Edge
When Mobile Blockchain Meets Edge Computing
Blockchain, as the backbone technology of the current popular Bitcoin digital
currency, has become a promising decentralized data management framework.
Although blockchain has been widely adopted in many applications, e.g.,
finance, healthcare, and logistics, its application in mobile services is still
limited. This is due to the fact that blockchain users need to solve preset
proof-of-work puzzles to add new data, i.e., a block, to the blockchain.
Solving the proof-of-work, however, consumes substantial resources in terms of
CPU time and energy, which is not suitable for resource-limited mobile devices.
To facilitate blockchain applications in future mobile Internet of Things
systems, multiple access mobile edge computing appears to be an auspicious
solution to solve the proof-of-work puzzles for mobile users. We first
introduce a novel concept of edge computing for mobile blockchain. Then, we
introduce an economic approach for edge computing resource management.
Moreover, a prototype of mobile edge computing enabled blockchain systems is
presented with experimental results to justify the proposed concept.Comment: Accepted by IEEE Communications Magazin
